Abstract: A device for bone fixation comprises an expansion part and a covering part. The expansion part has a fixing end and a top end and provides an expansion structure for being adjustable between a state of expansion and contraction. The covering part has a front end and a joining end, wherein the front end thereof is joined to the top end of the expansion part, and the joining end thereof is attached to the fixing end of the expansion part. The covering part is employed to cover the expansion structure. After the expansion part and the covering part are added to the bone, the covering part is unfurled to spread to the expansion state, and the medical filler is injected or pushed into the covering part.

Abstract: An artificial hip joint replacement system comprises a hollow fixation part having a joining end at a proximal end thereof and an injecting end at a distal end thereof, a cover part being joined with the injecting end of the hollow fixation part, a medical filling being forceable and/or injectable via the injecting end of the hollow fixation part and into the cover part, such that the medical filling is allowed to become lump-like after injecting is completed; a hip joint substitute being adapted to be joined with the joint end of the hollow fixation part and used for covering over a pre-finished femur; and an acetabular implant being adapted to be joined with the hip joint substitute to form the artificial hip joint replacement system.

Abstract: A device for treating vertebral bone including a releasably closed, removable filling member which can be placed within a plane separating superior and inferior portions of a vertebral body and oriented to promote its stabilization and realignment upon expansion of the filling member along the plane via injection of filler material, while minimally compacting bone or creating unsupported voids within the interior of the vertebral body.

Abstract: An extractable device is used to insert a medicinal filling into an animal tissue. The device comprises a filling member and a pasty medicine. The filling member is made of a flexible and hermetic wall and is provided with a holding portion and an injection port via which the pasty medicine is injected into the holding portion after the filling member is inserted into the animal tissue. The holding portion is provided with an opening which is releasably lashed by one end of one or more threads so as to make the opening leakproof. Upon completion of solidification of the pasty medicine in the holding portion of the filling member, other end of the thread is pulled to unlash the opening of the holding portion, thereby enabling the filling member to be extracted from the animal tissue so as to leave only the medicine in the animal tissue.

Abstract: The present invention provides a device for bone fixation that includes: an expanding unit and an enclosing unit. The expanding unit includes two or more expanding structures capable of switching between an expanded state and a contracted state. The expanding unit includes a first expanding structure located near a first end thereof and a second expanding structure located near a second end thereof. The enclosing unit encloses the expanding unit and has a first end and a second end. The first end of the enclosing unit is secured at the first end of the expanding unit, and the second end of the enclosing unit is secured at the second end of the expanding unit. When the device for bone fixation is placed inside a bone, the expanding structures of the expanding unit are switched to the expanding state and thereby propping up the enclosing unit.

Abstract: This invention relates to a method for operating on a spine, and more particularly to a method for operating on a spine by using a spinal fixation device which comprises the steps of (1) creating a hole on a vertebra; (2) placing said hollow fixation part joined with said cover part into the hole, and leaving the joining end of said hollow fixation part outside of the vertebra and exposed; (3) injecting said medical filling into said cover part via an injecting device and said hollow fixation part; (4) allowing said medical filling to become solidified so that said medical filling and the cover part form a lump; (5) removing said injecting device from said hollow fixation part.

Abstract: A device is designed to anchor a tissue to a bone. The device comprises a contractible implant, one or more sutures attached to the implant, and a pasty medicine capable of solidification. The implant is made of a flexible wall and provided with a holding portion and an injection port.
